What are the symptoms of a damaged supercharger?

The symptoms of a damaged supercharger are: blue or white smoke from the car's exhaust pipe, decreased power, increased engine oil, and unstable turbo pressure. The causes of supercharger damage are: 1. Foreign objects entering and damaging the impeller; 2. Impurities in the engine oil causing bearing and shaft wear; 3. Insufficient lubrication or aging of the lubricating oil in the turbocharger; 4. Use of inferior or deteriorated lubricating oil; 5. High exhaust temperature of the engine. The working principle of a supercharger: It utilizes the high-temperature exhaust gas (700 to 900 degrees Celsius) from the engine to drive the turbine in the turbo to rotate. The turbine shaft then drives the impeller in the compressor to rotate at high speed, compressing the air centrifugally and increasing the engine's intake air density to 2 to 3 atmospheres.
I've seen quite a few cases of supercharger failures, with symptoms mainly including noticeably reduced engine power—it feels like the car has lost its vigor, with sluggish acceleration and difficulty climbing hills. Abnormal noises are another major clue, such as a sharp whistling or howling sound near the engine when driving, which likely indicates issues with the turbine blades or seals. Changes in exhaust emissions are also common: blue smoke means oil is leaking into the combustion chamber and burning, while black smoke indicates an overly rich fuel mixture. At the same time, fuel consumption increases—I’ve personally experienced spending much more on gas, and the engine warning light often comes on. All these stem from internal wear or damage to the supercharger. If not addressed promptly, it can affect the entire engine's lifespan. I always advise friends to visit a repair shop early for a thorough diagnosis to prevent small issues from turning into big problems.
That day my car's turbocharger broke down, making the whole drive nerve-wracking. Usually stepping on the gas pedal gives lightning-fast acceleration, but suddenly it became sluggish with half the power output. Driving on the highway felt painfully weak. There was always this whistling sound coming from under the hood like a whistle - I didn't pay attention at first, but then blue smoke started coming out of the exhaust pipe and I panicked. Fuel consumption also jumped from an average of 10 liters to nearly 15 liters - money was burning way too fast. Finally, the mechanic said the turbo oil seal was leaking and needed replacement. I've learned that these small issues can really add up in cost, so now whenever I notice similar acceleration lag or unusual noises, I remind myself not to delay and get it fixed ASAP - saves both peace of mind and money.
Supercharger failure symptoms are particularly noticeable, with acceleration response as slow as an ox pulling a cart, and insufficient power making driving unpleasant. Strange whistling or howling sounds from the engine are usually signs of air leaks. Smoke from the exhaust pipe is even more dangerous—blue smoke indicates oil burning, while black smoke represents fuel mixture issues. These not only affect performance but also increase fuel consumption. From an enthusiast's perspective, after playing with cars for a long time, I recommend daily checks of fluids and connecting pipes to nip problems in the bud, but I don't advise randomly disassembling things yourself; it's safer to leave it to professional shops.
